flimsy i To all? whom it comes-n:

Be known that i: ee-rm J. flame-m and Fens/1w C. Aesoow boili citizens of the United Llta'tes reeicling at the city anti county of Sen Francisco sod State of Cell ffilllld. have invested new and useful Em movements in Rotary Valves. of which the following is s. specification.

This invention relates to a. rotary aive.

One of the objects of the present invention. is to PlOVlflE a simple form of rotary valve for internal combustion engines edeplecl be driven at a ratio of 1 to e the eagles ell-git. and provided with a single port which will alternately perform the required functions of admitting the charge, retaining" the same during the compression and ring stroke, and also permi: exlieusi, of the ex panded gases. Another object of iZlMB invenfiion is to rovide .a novel form of Water cooled valve head leaving alined exhaust and inlet passages formed therein. and an ad justaole ported bearing sleeve for reception oi the rotary valve. Another object of the invention is to provicle a friction drive through which the valve be driven. Further objects will hereinafter appear. I

The invention consists of the parts and the construction and combination of portsv as hereinafter more fully xiescribecl and claimed, having reference to the accompanying drawings, in Wliicl1-- Figure 1 is 11 side elevation partly in secon, of an internal combustion showng the application of the invention.

3. In an internal combustion engine, a cylinder head having an upper and a lower section, the lower section having its upper end exteriorly flanged and the upper section having 'its lower end exteriorly flanged and seated on the flanges of the lower section,

said sections having complementary passage-forming parts to provide a passage extending centrally and longitudinally through the head, and said parts being spaced from each of the respective sides of v the sections so as to be free of connection therewith, a machined hearing sleeve in the passage, inlet and outlet ports communicating with said passage, a valve in the sleeve formed to register with the inlet and outlet ports and means to secure said flanges together to clamp the hearing sleeve against movement.

i. In an internal combustion engine, a rotating valve for admitting and exhausting the gases, a sleeve on the valve having an extension, :1 driving member-having a bore receivable over the periphery of said vextension, said extension being split to form a pair of jaws, means to expand the iaws against the Wall defining the bore of the driving member, and means to drive the driving member.

5. In an internal combustion engine, a rotating valve for admitting and exhausting the gases, an extension on the valve, a driving member having a loore receivable over the extension, said extension being split to provide a pair of jaws, means to drive the driving member, and means to adjust the jaws whereby to regulate the degree of frictional contact between the member and extension so as to thereby control slippage between the member and valve. v
